Job description

Why us?

intent is a product development studio that partners with ambitious companies worldwide to design, build, and scale connected devices and digital experiences. Our vision has always been to grow the company in a smart way and not necessarily through headcount. Advancements in tools and LLMs open up a new chapter for us in this regard.

We are looking for a Cloud Fullstack Engineer (Frontend-focused) who will own the frontend but is also comfortable contributing to backend APIs, serverless functions and data workflows.

Our aim is to deliver seamless, data-driven experiences and dashboards for our customers — if you enjoy building complex UIs and visualizations while shaping the architecture behind them, this role is for you.

What’s cool about this job?

You’ll take ownership of a modern frontend stack in a cloud environment, work with real-time data visualizations at scale, and collaborate with a small, senior team.

About the role

This is a B2B/freelance role. We’ll give you clear objectives and a lot of autonomy — perfect for someone self-driven who enjoys crafting polished interfaces and also isn’t afraid to jump into backend/serverless code when needed.

You’ll work closely with other engineers, designers and product owners. We’re looking for someone who not only delivers features but also looks for smarter, faster ways of building things.

What you’ll do:

• Own our frontend architecture and implementation.
• Design and build new user-facing features using React.js and TypeScript.
• Contribute to backend app APIs, serverless functions and data integrations.
• Develop and integrate dashboards, visualizations and real-time data features.
• Ensure usability, accessibility and performance best practices (WCAG, ARIA).
• Help shape our logging and monitoring dashboards beyond Grafana (Datadog, New Relic, etc.).

Practical info:

• Contract: B2B / freelance
• Rate: 90 – 150 PLN net / hour (depending on your experience)
• Start: ASAP
• Engagement: long-term cooperation
